This mechanism calculates the coefficients of friction using an inclined surface. It does it by increasing the incline of the plane. This is done by a 30 kg-cm torqued motor with a 3D printed 7:24 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
